VRECONDITIONING CAR JOURNALS Vernon Wainscott, Lexington, Ky. Application September 3, 1936, Serial No. 99,307

1 Claim.

, My'invention relates generally to means for reconditioning car journals, and particularly to means for smoothing and truing the surface of such journals, and an important object of my invention is to provide means of the character indicated which enable the reconditioning of the car journals without removing the wheels.

Another important object of my invention is to provide a device for application to the car journals in the journal box and to be operated by hand or by a motor, for reconditioning the surface of the journal without removing the wheels or jacking up the car, so that a single operator may reconditionthe journal in an exceedingly short time, and eliminate the necessity for replacement of the journal bearing and of the journal'itself, or the removal thereof from the car at great expense of time and labor. 7

I Other important objects of my invention will be apparent from a reading of the following description taken in connection with the drawings, wherein for purposes of illustration I have set forth preferred embodiments of my invention.

In the drawings:

Figure 1 is a general longitudinal sectional view taken through a journal box and showing the journal therein with an embodiment of the invention applied thereto.

Figure 2 is a transverse vertical sectional view taken through the said embodiment and the journal.

Figure 3 is a plan view of the said support.

Figure 4 is a sectional elevational view of the invention. 7

Figure 5 is a transverse vertical sectional view taken on the line 5-5 of Fig. 4 looking in the direction indicated by the arrows Figure 6 is a plan view of one of the journal conditioning blocks.

Figure 7 is' a side elevational view of one of the journal conditioninghones. Figure 8 is "a bottom plan view of one of the journal conditioning files.-

Figure 9 is a longitudinal through one of the hones.

Figure 10 is an end view of the support shown in Figure 4. v

Referringin detail to the drawings, the numeral 5 generally designates the'journal box of I the railroad car through which extends the journal 6 which has in its axially outward end the centralized depression 1. In accordance with sectional view taken the present invention I employ two opposed jour- ,nal' conditioning blocks, each being of similar form and'respectively designated 8 and 9 which have a curvature concentric to the curvature of the journal 6 and which are of a sufficient length to extend the full length of the journal as indicated in Figure 1.

These blocks 8 and 9 have, on the radially in- 5 ward face thereof, either emery paper or sand paper with suitable means for attaching the same in place, or are provided as shown in Figure 2 with longitudinal beveled sided slots I I] and. II, respectively, which receive longitudinal hones or files, the hones being designated [2 and the files I3, the hones being arranged with a single cutting edge against the surface of the journal and the files being provided with a suitably cut fiat edge [4 applied against the surface of the journal.

The blocks 8 and 9 may have openings therein as shown in Figure 6 to secure the desired strength and weight and at the center of the resulting web is disposed the pair of lugs l5 which support the pivot l6 to which is pivoted the adjacent end of the corresponding one of the arms I! and I8. The opposite ends of these arms are bent at the points l9 and 20 and these portions are disposed in the slots 2| in the opposite end of the support 22, with the bend 28 under the anchor pin 23 which extends across the slot in the manner indicated in Figure 1. The pin 23 acts as a fulcrum for the arm when the arm is moved as presently described to adjust the tension of 30 the corresponding block 8, 9, against the surface of the journal 6.

The support 22 is elongated as shown in Figure 3 and has at its center a square opening 22 through which is passed a square shaft 36 with a 35 suitably rounded terminal 31 to engage the depression l in the end of the journal 6.

Smooth pins 24a work in the smooth bores 25a in the bottoms of the slots in the ends of the support 22, and these pins are pivoted as indicated by the numerals 3| to the outer ends of links 32 which are pivoted at their inner ends as indicated by the numerals 33 to the yoke 34 which is fastened to the square tube 35 which slides on the exterior of the square shaft 36. A 5 helical compression spring 38 is interposed between the outer end of the squared shaft 36 and the closed end 39 of the tube 35. A chuck received shank 40 is arranged on the end of the tube 35 for connection with the shaft 29 of a suitable motor 30 through chuck receiving portion 28. In the use of the invention pressing in on the motor will press the tube 35 against the resistance of the spring 38, toward the journal 6 in a manner to cause the links 32 to spread and force the pins 24a in a radially outward direction and thereby secure proper compression by the arms I! and I8 on the conditioning blocks 8 and 9 against the sides of the journal. Operation of the motor 30 will rotate the support 22, arms l1 and I8 to revolve the blocks 8 and 9 around. the journal 6 and properly condition said journal.

Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of the invention thereto, and any change or changes may bemade in the materials, and in the structure and arrangement of the parts, within the spirit of the invention and the scope of the subjoined claim.

What is claimed is:

Apparatus for grinding a car journal having an axial centering socket in the outer end thereof comprising a motor, a shaft to one end of which the motor is operatively connected, a centering pin extending from the opposite end of the shaft for location in said socket to center said shaft axially of the journal, said opposite end of the shaft being cylindrical and telescoping over said pin whereby said shaft is slidable on the pin toward and from said end of the journal, a tension spring in said cylindrical end of the shaft 0pposing movement thereof in one direction, a cross head fast on the cylindrical end of the shaft,

a pair of arms pivotally mounted at one end on said cross head to extend along diametrically opposite sides of the journal and for adjustment toward and from the latter, a pair of plates pivoted to the opposite ends of said arms for adjustment by the latter toward and from the journal and having abrasive means thereon, and means to adjust said arms toward said journal under movement of the shaft toward said end of the journal comprising a pair of toggles connected to said cylindrical end of the shaft and said arms, respectively.
